WINDOW STAY Filed Jan. 27, 1928 Patented July 30, 1929 WINDOW STAY.

Application filed January 27, 1928, Serial No. 249,954, and in New Zealand July 1, 1927.

This invention relates to stays and fasteners for casement windows of the type in which a link is pivoted to a bracket fixed to the window sash and the stay bar pivoted in such link, so that when such window is closed the stay bar will lie at right angles to the link and parallel with the sash. i

The object of the present invention is to draw the sash inwards and lock it in position, and also to improve the construction of such devices and render them more efficient.

Accordingtothe present invention, the bracket fixed to the window frame is formed with a shelf or, hook in which the stay is adapted to ride, while above the shelf or hook and in alignment therewith, a locking pin is guided and adapted to be actuated by a cam shaped end upon-the pivoted end of the stay bar, the upper end of such locking pin being adapted to enter an opening in a projectinglug of a bracket fixed to the sash.

If desired, the fastening pin may be under the influence of a spring normally tending to return the fastening pin from engagement with the lug, and also tending to cause the pin to bear upon the edge of thestay bar and retain it in engagement with the shelf or hook by means of openings or the like at intervals in the bar which en age a pin or the like projecting from the shelf or hook.

The invention will be described with the aid of the accompanying drawings, wherein Figure 1, is a front elevation, and

Figure 2, is a side elevation showing the stay in 'position'upon a window frame and showing the sash closed and fastened.

Figure 3, is a partly sectional side elevation showing the stay in a horizontal position and having a jointed portion thereto.

Figure 4, is a side sectional elevation showing the stay in a similar position as in Figure 2.

Figure 5, 1s a similar'view to Figure 3.

Figure 6, is a'view of a detail.

Referring to the drawings, a bracket 1 which is fixed to the window frame 2 is formed with a hook 3 in which the stay bar '4 is adapted to ride, such stay barbeing pivoted on a 13111 5 111 a link 6 pivoted on a pin- 7 in aws 8 of a bracket 9 fixed to the sash 10 by screws 11. Above the hook 3 and. in alignment therewith a fastening pin 12 is carried ina housing '13 formed integral with the bracket 1 as shown. The pin'12 has an enlarged end 14 sliding in an opening in the lower end of the housing and a shoulder 15 on the pin limitsv the downward movement of the pin upon the internal shoulder 16 of i housing 13, the pin 12 being guided through such nut as shown in Figure 4. The upper end 19 of the pin 12 passes into an opening 20 in a projecting lug 21 of the bracket 9. The opening 20 is tapered so thatas the pin 12 is forced up, the tapered end19 will tend to draw the bracket 9 in an inwardly direction, as indicated by the arrow in Figure 4, and thus tighten the sash against the frame. The end of the stay bar 4' has a cam face or extended portion 22 so that as the bar is being turnedtowards a position at right angles to the link 6, as shown inv Figures 2 and 4, this cam face 22 engages. beneath the enlarged part 14 of the pin 12 and presses the pin upwards so that when the sash is closed the tapered end 19 of the fastening pin being forced into the tapered opening 20 tends to draw the sash tighter against the rabbet of the Window frame. The bar 4 will have a number of holes or openings 24 upon its underedge to engage a stub pin 25 projecting from the hook 3, the bar being re turned in engagement with the stub pin by pressure of the pin 12 on the upper part of the stay. and is adapt-ed to enter the tapered holes 24 in the stay bar so that under pressure of the spring 1.2, or even under the weight of the bar itself, there will beno rattling of the. bar on the pin. shown in Figures 2 and 4 enters between the jaws of the link.

To manuallyoperate the pin 12 such pin may have a handle 26 projecting from it through a vertical slot 27 in the housing handle 26 to the position shown in Figure 2 This stub pin is taperedas shown The stub pin in theposition and will be held in engagement with the 2 portion 21 irrespective of the cam end 22 and thus retain the window fastened independently of the stay bar 4. The edge of the slot 28 may slope so that as the handle is turned gradually reducing,

a further upward movement of the pin 12 will occur. the housing on each side of the slot may be tapered towards the slot slightly cam faced as at 38, so that by rotating the handle 26 (as in Figure when the locking pin is bearing on the bar 4, such bar may be fastened in position on the hook. In cases where the spring 17 is not used this construction is very desirable.

The stay bar may be knuckle-jointed as shown in Figures 1 and 3, in which case the end portion of the bar 29 is bifurcated to form jaws 30 and the reduced portion 31 of the bar 4 has a shoulder 32 which is inserted in the bifurcation and pivoted on a 1) may be curved in order to allow the angle movement of the stay bar due to the opening of the sash. 1

The stay at the portion from the sl'ioulder 36 has its under edge cut away at. 37 in order to clear the pin 25 when the bar 4 is in the position shown, in Figure- '3, and as indicated by the dotted lines terminating near the first hole 24 so as to avoid lifting the bar unduly to clear the pin 25 when openingthe sash outwards. The stay is left'full width on each side of the incline 37 in order to provide a shoulder to take the thrust of the bar against the hook 3 when the stay is brought to the position shown in Figures 2 and 4 to close the sash in order to permit the pin 12 to engage the opening 20.

Instead of the handle 26 being employed to retain thefastening pin in position, the stay may engage a catch fixed on the window frame, or such catch may be formed on the lower portion of the bracket 1.

What I claim is 1. In a window stay and fastener, a window bracket, a fastening pin guided in said bracket, a stay slidably engaging the bracket and having a'cam face coacting with thepin to move the latter longitudinally, and a sash bracket having a slot to receive the pin and securing the stay.

2. In a window stay and fastener, a window bracket, a fastening pin guided in said bracket, a stay slidably engaging the bracket and having a cam face coacting with the pin to'move the latter longitudinally, and a sash bracket having a slot to receive the pin, and means pivotally connecting the slidable stay to said-sash bracket.

3. In a window stay and fastener, a window bracket,'a fastening pin guided in said bracket, a stay slidably engaging the If desired, the under edge of bracket and having a cam face coacting with the pin to move the latter longitudlnally,

and a sash bracket having a slot to receive the pin, and means pivotally connecting the slidable stay to said sash bracket, and means independent of said stay for maintaining the fastening pin in said slot.

'4. In a window stay and fastener, a window bracket, a fastening pin guided in said bracket, a stay slidably engaging the bracket and having a cam face coacting with the pin to move the latter longitudinally, and a sash bracket having a slot to receive the pin, said stay being attached to said sash bracket and means carried partly by the window bracket and partly by the stay for 'maintaining the latter in various adjusted positions relative to the window bracket.

5. In a window stay and fastener, a window bracket, a fastening pin guided in said bracket, a stay slidably engaging the bracket and having a cam face coacting with the pin to move the latter longitudinally, and a sash bracket having a slot to receive the pin, and means pivotally connecting the slidable stay to said sash bracket, means carried partly by the window bracket and partly by the stay for maintaining the latter in various adjusted positions, andmeans normally tending to engage the pin with the stay whereby to resiliently maintain the latter in engagement with the window bracket.
